IMPROVEMENT lN RAILWAY-RAIL CHAIRS.

Specification forming part of Letters Patent No. 141,275, dated July 29,1873; application filed June 28, 1873.

To all whom it may concern:

Be it known that I, SAMUEL HUBER, of Danville, in the county'of Montourand State of Pennsylvania, have invented a new and useful Improvement inRail-Joints, of which the following is a specification:

The main object of this invention is to prevent the ends of the rails ofrailroad tracks from being battered or damaged by passing trains; and itconsists of a cavity or recess beneath the joint of the rails, whereby acertain degree of elasticity is allowed the ends of the rails.

In the drawing, Figure 1 represents a side view. Fig. 2 is asectionaltop view ofthe chair, and Fig. 3 is a vertical cross-section of Fig. 1taken on the line 00 x.

Similar letters of reference indicate corresponding parts.

A is the chair; B, the rails. D represents the joint of the rails. D isthe bed upon which the rails rest. E is the cavity made in this bedbeneath the joint, between the bearin gsurfaces F F.

The chair may be made in any manner so that the cavity E is secured. Itmay be made in two or more pieces, either of cast or wrought iron orsteel. In this example of my invention I make the chair in two piecesand fasten the parts together with one or more spikes or bolts. The formof the chair is seen in the cross-section, Fig. 3.

G is a fastening bolt or spike.

The chair is cut away in the parts which hold the bed-flanges of therail, as represented at H in the drawing, which leaves additionalstrength at the ends of the chair to support the bearing-surtaces at FF, as seen at I.

The rails of a railway always fail at the ends first; the ends beingsupported on a solid hearing, there is no elasticity,-and the continualpounding of the wheels batters and brooms up the ends, and soon rendersthe rail unlit for service unless repaired. By allowing the ends to givein a slight degree their battering is prevented and the rails arepreserved.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- A rail-chair having a cavity or recess, substantiallyas seen at E, as and for the purposes described.
